In situ characterization for atmospheric reenty materials

Atmospheric reentry is one of the most severe conditions for materials. During this short period (5-15min), several reactions take place at the surface of thermal protection systems. The high surface temperature (above 2500°C), high speed and oxygen presence lead to ablation and oxidation phenomena. Understanding all the phenomena which take place during the atmospheric reentry is very difficult. One of the best ways to study it is in situ micro-tomography. For these experiments, synchrotron radiations are mandatory for fast and high-resolution tomography’s reasons.
